More Information

Curtiss-Wright / VMETRO / Micro Memory MM-6490R High Speed, Dual-Port 256MB VME / VME64 / RACEway Buffer Memory Overview

Features:

  • 128MB, 256MB, 512MB, 1GB and 2GB Capacity
  • 32-bits for VMEbus and RACEway
  • 8, 16, 32, 64 bits (UAT) for VMEbus
  • 32-bit Multiplexed for RACEway
The MM-6490 series high-speed, dual-port memory module that provides up to 2GB for VME/VME64/RACEway systems. It is intended for high performance applications employing Burst Mode on RACEway at data rates greater than 160 Mbytes/sec. Block Transfers on the VMEbus with data rates at 80 Mbytes/sec are also supported.

The Control Status Register (CSR), located in the short I/O address space, stores and reads bytewide parity errors detected on the VME/RACEway buses. The other bits enable Write-Wrong parity for diagnostics.

Parity generation and checking are provided for each byte; parity status is stored and transmitted via BERR.

Reliability is ensured by burn-in and running memory diagnostics that check operation for 48 hours while temperature cycling boards from 0-60° Celsius.

The Micro Memory MM-6490R High Speed, Dual-Port 256MB VME / VME64 / RACEway Buffer Memory may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
